Abstract
Closed form expressions for the bit error rate (BER) performance of the down link of the space- frequency block-coded multiple input multiple output code-division multiple-access (SFBC-MIMO-CDMA) systems are derived and evaluated. The effects of channel estimation errors on the BER are studied. Rayleigh fading channels are considered. We consider both the M array phase shift keying (MPSK) and the M array quadrature amplitude modulation (MQAM) techniques. We compute the analysis results for a wide range of the various parameters involved (M-array size, number of OFDM carriers ....etc) as well as different SFBC-MIMO-CDMA configurations. Such evaluations are crucial not only for system performance prediction, but also for network management, monitoring and future cross-layer design.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
